A duo-activity enzyme for one-step biodesizing and bioscouring process of cotton fabrics and a portable aflatoxin sensor won Gold Prizes at the Seoul International Invention Fair (SIIF) 2013.

ENZease is a duo-activity enzyme for one-step biodesizing and bioscouring process of cotton fabrics. It is composed of amylase and pectinase activities which are capable of working at the same pH and temperature range. It was established to replace the conventional chemical process and combine the desizing and scouring steps of cotton fabrics. The use of ENZease provides many benefits that could not be obtained from the conventional two-stage pretreatment process using chemicals and/or other commercial single-activity enzymes currently available in the market. In addition, ENZease is able to lower chemical consumption, minimize step in the process, shorten treatment time, and also reduce operational cost and space, which will make the large-scale operations more simple and cost effective. ENZease was co-developed by BIOTEC, in collaboration with MTEC and Thanapaisal R.O.P.

AflaSense is a novel, low-cost and portable tool for simple and rapid aflatoxin detection, originated from a joint project between NECTEC and BIOTEC. AflaSense operation is based on the measurement of current response as a result of electrochemical reaction from aflatoxin on an innovative grapheme-based test stripe fabricated by printing technology. The current is then accurately converted into aflatoxin concentration and output on the built-in LCD display. The disposable graphene electrode offers high efficiency, high detection sensitivity and wide aflatoxin detection range 0-80 ppb (maximum contaminated level of aflatoxin = 20 ppb).

Apart from Gold Prize, AflaSense is awarded a special prize from International Warsaw Invention Show (IWIS)supported by Association of Polish Inventors and Rationalizers at SIIF 2013 as well.

Seoul International Invention Fair (SIIF) 2013 was organized by The Korea Invention Promotion Association (KIPA) on 29 November - 2 December 2013 in Seoul, the Republic of Korea. It is one of the world's largest international invention fairs. This year, there were a total of 710 inventions from 31 countries entering the competition. The National Research Council of Thailand nominated 50 inventions from Thailand to participate in the competition, taking home 1 grand prize, 13 special awards, 15 gold prizes, 14 silver prizes and 19 bronze prizes.
